Joel Courtney Success! - March 3rd, 2015I actually got my prints back in January but am appalling at getting around to doing things!
After a period of about a year (!!!) finally posted a LOR to Joel along with 4 prints (printed off a well known fishphoto place ). I put these in LE along with a LAE. Had to take a gamble as UK has stopped the IRC's. So had to hope Joel would be able to stick a stamp on at other end!
Received a reply very very fast considering it was Christmas at all. Like an idiot I threw away the envelope used as I am like that!! I would say period was Dec 17th from postage to mid January. I used the address here:
Joel Courtney
676 West Pullman Rd.
Suite 301
Moscow, ID 83843-2061
USA
There was only a tiny bit of personalisation with no letter but I was more than happy with the photos He is such a nice guy to pay for postage too!
